IN SEARCH OF DIRECT REALISM Laurence BonJour
University of Washington
It is fairly standard in accounts of the epistemology of perceptual knowledge
to distinguish three main alternative positions: representationalism (also called
representative realism or indirect realism), phenomenalism, and a third view that is
called either naïve realism (usually by its opponents) or direct realism (usually by
those who are more sympathetic to it). I have always found the last of these views
puzzling and elusive. My aim in this paper is to try to figure out what direct realism
amounts to, mainly with an eye to seeing whether it offers a genuine epistemological
alternative to the other two views and to representationalism in particular. My
thesis will be that it does not—that what is right about direct realism turns out to
have little bearing on the main epistemological issue concerning perceptual
knowledge.
Both for reasons of space and to allow a focus on the issues that I regard as
the most important, my discussion will be restricted in the following ways: First, I
will give no consideration at all to phenomenalism. The numerous and to my mind
entirely decisive objections to the phenomenalist view are by now very well known.
Second, I will also give no attention to the standard externalist views of justification,
of which reliabilism is the most familiar. Though it is very easy within a reliabilist
framework to defend something that might perhaps be characterized as “direct
realism,” the point of such a characterization and of the alternatives that it
implicitly suggests is largely lost in that context. Third, although I started by
speaking of perceptual knowledge, I will pay no real attention to the concept of
knowledge as such, focusing instead on the issue of whether and how perception
2
yields a good reason or basis for thinking that a belief about the material world is
true—the issue of justification, as at least one version of internalism understands
it.1 Fourth, I will follow the usual philosophical practice of concentrating mostly on
visual perception, adding, as is also usual, that I am reasonably confident that the
resulting discussion could be generalized without any crucial modification to
perception via the other senses. (Perhaps it is worth adding that I am interested in
direct realism as a serious epistemological alternative that offers an account of how
perceptual beliefs are justified, not merely as the denial that this issue need be
taken seriously.)
Thus the main issue to be considered is whether there is a genuine direct
realist alternative to representationalism, one that is at least prima facie viable,
with regard to the sort of reason or basis we have or might have for thinking that
the beliefs about the physical world that result from perception, especially visual
perception, are true. (Hereafter the terms “justification” and “justified” will be used
exclusively in the indicated internalist sense that pertains to the possession of a
good reason or basis for thinking that a belief is true.)
I I begin with an elaboration and clarification of the contrast between direct
realism and representationalism, starting with the latter. In first approximation,
the representationalist holds two main theses: first, that what is perceived directly
or immediately in sensory experience is not “external” physical or material objects,
but rather things that are mental or subjective in character—sense-data or sensa,
according to the most standard versions of the view; and, second, that the only
available (reasonably cogent) reasons deriving from perception for thinking that
perceptual beliefs about the physical world are true depend on inference from facts
3
about these directly perceived mental or subjective objects, i.e., from facts about the
character and contours of subjective sensory experience, to conclusions about
physical or material objects. (Notoriously, what “direct” and “immediate” mean in
these formulations is far from obvious and will have to be considered further
below.)2
What then does direct (or naïve) realism amount to? The direct realist
should, I suggest, be viewed as rejecting both of the characteristic theses of
representationalism, while still maintaining that perception is indeed a source of
justification for beliefs about the material world. This commits the direct realist to
holding both: (a) that in normal cases of perception, physical or material objects are,
in a sense admittedly still in need of clarification, directly or immediately perceived;
and (b) that the justification for beliefs about such objects that results from
perception does not depend on the sort of inference from the subjective character of
perceptual experience to which the representationalist appeals, but can be accounted
for in some other way. It is obviously the former of these theses that gives direct
realism its label; but the latter thesis is far more important from an epistemological
standpoint and provides the main dialectical motivation for the view. For the main
alleged virtue of direct realism has been precisely that it avoids the need for the
allegedly difficult and perhaps even hopeless inference to which the
representationalist view appeals.
Here is it important to see clearly from the beginning that an adequate case
for the second direct realist thesis cannot be made merely by raising problems for
the representationalist’s opposing view. No matter how difficult or even seemingly
impossible the representationalist’s attempted inference from subjective experience
4
to the material world may turn out to be, this is not enough by itself to show that
direct realism provides a better epistemological alternative. Thus the only way to
adequately defend the second direct realist thesis is to actually give a competing
account of how perceptual beliefs about material objects are justified, presumably by
appealing in some way to the direct or immediate experience of such objects that is
alleged in the first direct realist thesis. And until and unless such an account is
given, a direct realist victory with regard to the issue defined by the opposing first
theses would amount to very little, at least from an epistemological standpoint, since
it would still leave the representationalist’s account of reasons for perceptual beliefs
as the only apparent contender in the field (phenomenalism aside), however
allegedly problematic it may be.
From this perspective, it is a striking fact that many of the recent
proponents of direct realism offer little or nothing by way of a positive account of
how perceptual beliefs are justified according to their view, concentrating instead on
defenses of their first thesis and on arguments against the two representationalist
theses. Thus, for example, George Pitcher, in his defense of direct realism in his
book A Theory of Perception, expresses the assumption that direct realism “is the
most desirable sort of perceptual theory from an epistemological point of view,”3 but
never gives any real explanation of how and why this is supposed to be so, of just
what the direct realist epistemological account amounts to. Similarly, in D. M.
Armstrong’s earlier book Perception and the Physical World,4 arguments are
mounted at great length against representationalism (and against phenomenalism),
focusing mostly on the issue defined by the opposing first theses. But the only hint
of a positive account of how perceptual beliefs are justified or rationally acceptable
5
consists in an appeal to the regress argument for some form of foundationalism,
leading to the conclusion that “There must be at least some truths that we know
without good reasons,” together with the further remark that
. . . since immediate perception is, avowedly, the court of last
appeal when it comes to questions about physical reality, there is
no objection, it seems, to saying that in immediate perception at
least, we acquire knowledge of certain facts about the physical
world without good reasons.5
This may point in the direction of Armstrong’s later externalist view,6 but it offers
no help at all in our search for an internalist account of how perceptual beliefs are
justified according to direct realism, saying at most, perhaps, that such an account
ought from an intuitive standpoint to be available.
Many other recent defenses of direct realism do no better in this regard.
Jonathan Dancy, in his book An Introduction to Contemporary Epistemology,7
ostensibly opts for direct realism for reasons that are again based mainly on
supposed problems with the competing views, and then somewhat surprisingly
suggests a coherentist account of how perceptual beliefs are justified.8 For reasons I
have discussed elsewhere,9 I am extremely doubtful that any such view can succeed.
But for now it is perhaps enough to point out that it really amounts to a denial that
perceptual experience as such offers any justification for the beliefs that result from
it, rather than an account of how such justification works, so that Dancy’s view is
not really a version of direct realism as I am understanding it here. John Searle, in
his book Intentionality,10 argues for the intentionality of visual experiences, claiming
that such experiences both are about material objects and constitute presentations
6
rather than mere representations of such objects, an idea about which I will have
more to say shortly. He also argues briefly against phenomenalism and
representationalism, though his arguments against the latter view are not
particularly compelling. But to the issue of what reason or basis we have on the
basis of perceptual experience for thinking that this intentional, presentational
content is true, Searle has virtually nothing to say. And while both Hilary Putnam
and John McDowell offer views that seem to be intended as versions of direct
realism,11 it is again hard to find in either of their accounts any real response to the
issue of how perceptual beliefs are justified.
II I turn to a consideration of the issue defined by the first of the direct realist
and representationalist theses. Here it is very easy to make a case for the
correctness of the direct realist thesis on at least two fairly obvious understandings
of the terms “direct” or “immediate.”
Consider, first, the question of whether our perceptual awareness of material
objects is arrived at via explicit inference from either beliefs about or awarenesses of
subjective entities such as sense-data. Certainly some representationalists,
especially earlier and less cautious ones, have said things that suggest such a view.
But it is entirely too obvious to be denied that in ordinary cases there is no
consciousness at all of such an inference—and that appeals to “unconscious
inference” are mere evasions of the question. In most ordinary situations, it is
material objects and situations that are the primary or usually the exclusive objects
of the perceiver’s explicit awareness and thought, with no hint that this awareness
has been arrived at via a transition from anything else. In fact this point is so
obvious as to make it hard to see how an explicit inference view could be plausibly
7
ascribed to any serious philosopher, and for this reason, it seems to me preferable
not to view even representationalists as committed to such a claim. This is not to
say that the perceiver is not also conscious in some way of, in the visual case, the
patterns of color and shape that philosophers have characterized in terms of
subjective sense-data or adverbial feature. But this is normally very much in the
background and not at all the object of explicit attention.
Second, as Searle seems to have in mind in speaking of “presentation,” there
is in addition an obvious and intuitively compelling way in which my perceptual
experience seems to directly present physical objects and situations to me: given
suitable conditions of lighting and so forth, I have only to open my eyes, and there
they are, in a way that seems completely open to my cognitive access. I find it
somewhat difficult to say clearly what this direct presentation of physical objects
really amounts to, but it is undeniably a feature of the phenomenology of perceptual
experience, one that would not automatically follow from its non-inferential
directness alone. (It seems reasonably clear that ordinary beliefs about material
objects are less than fully direct, in that they are based on—though not in any clear
way inferred from—these more basic presentational awarenesses.)
We thus have at least two reasonably clear senses in which the perceptual
awareness of material objects can be said to be direct, thereby establishing a case for
the first of the two direct realist theses. But what about the second thesis, which I
have argued to be epistemologically more fundamental? Do either of these ways in
which perceptual awareness of material objects is direct yield any clear alternative
to the representationalist’s account of how claims about such objects must ultimately
be justified?
It is easy to see that the non-inferential character of perceptual awareness
8
says nothing positive about the issue of justification, but merely rules out one way in
which the resulting claims might have been justified. A sheer hunch or random
thought is after all also non-inferentially arrived at, but that plainly constitutes no
reason for thinking that it is correct and so no basis for justification (though we will
consider below a view that seems to dispute this).
What about the presentational directness of perceptual awareness? It is easy
to see how the way in which material objects seem to be simply presented or, as one
might even be tempted to say, given in perceptual experience could lead to the view
of at least the most naïve level of common sense that there is no problem at all about
the justification or indeed about the truth of the resulting beliefs. But as long as the
presentational character of perceptual experience is not confused with the more
Cartesian version of immediacy that I will consider momentarily, it is far from clear
why it should be accorded any genuine justificatory force. This presentational
character has to do with the way in which physical objects are represented or
depicted in experience, but has no obvious bearing on whether such representations
or the beliefs that reflect them are true. A presentational representation is no doubt
more vivid, more striking, in something like the way in which a picture is more
compelling than a merely verbal description. But pictures are just as capable of
being mistaken as anything else,12 and so the pictorial character of a representation
seems to be simply irrelevant to the issue of justification; my suggestion is that we
have so far seen no clear reason not to say the same thing about the presentational
character of perceptual experience.13
In thinking about the foregoing point, it is useful to explicitly contrast the
presentational directness or immediacy just described with the further, more
9
controversial notion of directness or immediacy that has been advocated by
epistemologists in the broadly Cartesian tradition. According to this Cartesian view
of immediacy, sometimes referred to as “acquaintance” or “givenness,” mental and
sensory states and the objects that they are taken to involve are directly accessible
to consciousness, directly before the “eye” of the mind. This view has often been
accompanied by a claim that mistake about them is entirely impossible, but it is
important to see that this is at best a consequence of the main view, not its central
core. The central idea, I suggest, is rather that such entities and features are simply
part of the content of consciousness itself, so that the most fundamental
consciousness of them, that by virtue of which they exist at all, could not indeed be
mistaken. Even if this were so, it would not preclude the formation of mistaken
beliefs about this content as a result of confusion or inattention or bias of some sort,
but would still provide a clear basis for justification, in that the content of such a
belief could be directly compared in consciousness to the conscious feature or object
that it purports to describe.
Notoriously many recent epistemologists, including most of the proponents of
direct realism, have been highly critical of this Cartesian picture, skeptical about
whether anything is genuinely given to consciousness in the way that it claims. My
own view, developed elsewhere, is that the Cartesian view is defensible and even
obvious if properly understood.14 But my point for the moment is that whether or
not such a view is defensible in relation to our awareness of the features or aspects
of sensory and mental states, it is plainly not applicable to our perceptual awareness
of material objects. Material objects, understood in a realist, non-phenomenalist
way, are plainly outside the mind, metaphysically distinct from any sort of
10
experience or awareness of them, and related to conscious experience only via a
highly complicated causal chain. They are thus inherently incapable of being
directly given to consciousness in the way that things like sense-data are claimed by
the Cartesian to be—a point that should, of course, be readily accepted by those who
think that the Cartesian brand of directness or immediacy is simply a myth and so
does not genuinely apply to anything. This means that even the most fundamental
perceptual awarenesses of material things are entirely distinct from their objects in
a way that allows room for the issues of correctness and of justification to be
significantly raised and precludes the simple response that a Cartesian version of
immediacy might seem to make available.
If the Cartesian version of directness or immediacy should turn out, as I
believe, to be more than a myth, then there would be a clear sense in which
perceptual awareness of material objects is not direct, in addition to the others,
already noted, in which it is direct—so that the issue between the first of the direct
realist and representationalist theses would end in a split decision. But the more
important point is that even if the senses in which the perceptual awareness of
material objects is direct and immediate are the only viable ones, we have so far
found no way in which this result provides any clear support for the crucial second
thesis of direct realism. Even if the perceptual awareness of material objects is
arrived at without inference, and even if the objects in question are from a
phenomenological standpoint simply presented in our perceptual experience, neither
of these forms of directness or immediacy seems in any very obvious way to yield a
good reason or basis for thinking that the resulting claims about the physical world
are true or likely to be true. It thus remains so far quite possible that the account of
such reasons offered by the second representationalist thesis is the only one
11
available.15
It will not have escaped notice that I have arrived at this result with very
little consideration along the way of specific direct realist views. I have already
noted that many such views say almost nothing about the crucial issue of
justification, but there are others that do address that issue more explicitly, and I
now want to have a look at some of these. A full consideration any of them would
require much more space than can be allotted here, but fortunately their responses
to the key issue of justification can be dealt with fairly briefly.
III Perhaps the simplest and most straightforward response to the issue of how
perceptual beliefs about material objects are justified is offered by Michael
Huemer.16 According to Huemer, perceptual experiences are “assertive mental
representations,” where what is thus represented is some sort of specific physical
object or situation. When there is genuine perception, such experiences count as
awarenesses in Huemer’s defined sense, in that (i) there exists an object or situation
that satisfies the content of the experience, and (ii) it is non-accidental (as a result of
a non-deviant causal chain) that this is so [79-80]. And such awarenesses are direct,
he claims, because they are not based upon any other sort of apprehension [80],
where one apprehension A is based on another apprehension B just in case B causes
A because B appears to logically support A [56]. Perceptual beliefs, involving
conceptual claims about physical objects and situations, are based upon such
perceptual experiences, but not inferentially, since inference is a relation between
beliefs, and perceptual experiences are not beliefs: though they have propositional
content (that is, are true or false), that content is not conceptually represented
[74].17 Though there are several questions that might be raised about this view, it
12
seems to me reasonably plausible so far, for reasons that we have already seen:
perceptual experience does seem to involve presentations of material objects that are
capable of being true or false; and these do not seem, at least in general, to be
arrived at on the basis of other apprehensions.18
But all this only raises, or at least appears to raise, the further issue of
whether and how the perceptual experience, or perhaps rather the assertive
representation that it involves, is itself justified: that is, of what reason if any there
is to think that this representation is true or correct. To this pivotal question,
Huemer offers, as I see it, two rather different responses, one directly and one by
implication, neither of them in my judgment adequate.
The first, more direct response is to deny outright that the issue of
justification intelligibly arises for perceptual experiences. According to Huemer, “It
does not make sense—it is a category error—to say that an experience is justified or
unjustified” [97]. People simply have experiences, but cannot be either justified or
unjustified in having them because they are simply “automatic responses to external
stimuli” [97]. But this is almost entirely misdirection. While it is of course true that
people cannot help having perceptual experiences, so that it cannot be intelligibly
said that they should not have had them or are somehow blameworthy for having
them, none of this has any real relation to the main epistemological issue with which
we are concerned. On Huemer’s own account, such experiences have an assertive
representational and indeed propositional content: they represent various specific
objects and situations as existing in the world. But then we can surely ask quite
intelligibly what reason or basis, if any, there is for thinking that the
representational content in question is true or correct, that is, for thinking that the
13
world actually contains the objects or situations thus represented—and this just is
the question of whether the perceptual experience, or more specifically its
representational content, is justified in the sense I have indicated.
Huemer, to his credit, recognizes that this first response to the question of
the justification of perceptual experiences will not do by itself. He thus advances a
further account of why beliefs that are based on perceptual experiences are
themselves justified, even though the experiences themselves are neither justified
nor unjustified. This account appeals to a principle called “the rule of Phenomenal
Conservatism”
If it seems to S as if P, then S thereby has at least prima facie
[that is, defeasible] justification for believing that P. [99]
Here the relevant seeming is the perceptual experience itself.19
But is this principle, which Huemer claims to be a self-evident necessary
truth, in fact correct? I do not have space here to consider everything that Huemer
says in support of it, but the main lines of his defense can, it seems to me, be
captured in the following two claims: First, the principle represents “the
epistemological default position,” in that seemings or appearances are “presumed
true, until proven false,” which he compares to the legal situation in which a
criminal defendant is “presumed innocent, until proven guilty” [100]. Second, “all
thought and reasoning presupposes the principle in a certain sense” [105], in that
there is ultimately no alternative but to rely on what seems to be true, no other
place for reasoning and dialectical criticism to start. And the problem is that neither
of these claims speaks nearly clearly enough to the fundamental issue of whether
there is any reason or basis for thinking that the seemings in question are likely to
14
be true.
This is a bit easier to see with respect to the first claim, where it seems
obvious that neither the computer metaphor (for that is really all it is) nor the really
quite irrelevant legal analogy provides any real insight as to why the claims in
question should be “presumed true” if this is supposed to mean that there is a good
albeit prima facie reason for thinking that they actually are true. Though others
have also made similar suggestions, it just isn’t clear why there should be an
“epistemological default position” of this sort or why there should be an allocation of
the burden of proof that favors the truth as against the falsehood of such a claim.
(And if the presumption is supposed to be reasonable in some other, non-epistemic
way, then it seems simply irrelevant to the issue of epistemic justification.)
As regards the second claim, I am inclined to agree with Huemer that in the
end we have no alternative in our thought and reasoning but to rely on things that
seem to us to be true. Any sort of reasoning or discursive justification must start
somewhere, and it is far from obvious what other sort of starting point there could
be. The important question, however, is whether all forms of seeming are on a par
in this respect, at least to the extent of constituting prima facie reasons for thinking
that the claims are true, as Huemer’s principle claims, or whether it might instead
be the case that some specific ways of seeming constitute reasons of this sort and
others do not. It is easier to argue for the negative part of this latter alternative, for
it surely seems clear, contrary to Huemer, that, for example, a mere spontaneous
hunch provides no reason for thinking that its content is true, no matter how
psychologically compelling it may be. Making a case for the positive part, viz., the
claim that certain specific sorts of seemings do yield genuine reasons, is harder and
cannot be attempted here; I have argued elsewhere that this is true for at least two
15
sorts of seemings, those that involve apprehensions of the contents of one’s own
conscious states of mind and those that involve apprehensions of self-evident
necessary truths.20
But my main point for the moment is that until and unless such a case can be
made, either for some particular sorts of seemings or for all, the fact that we
ultimately have nothing else to rely on does not show that the claims that we accept
on this basis are likely to be true or that we have any good reason to think that they
are. That we have nothing better to rely on, even if this is (as I doubt) genuinely the
case, does not show that the best we have is good enough. Thus if Huemer’s defense
of the reliance on perceptual experience is the best that we can do, the result, I
submit, is skepticism about the resulting claims rather than genuine justification.21
(It is also worth noting the rather surprising fact that the distinctively perceptual
character of the experience really plays no role in Huemer’s account of how the
resulting claims are justified.22)
IV A quite different account of the justification of claims about material objects
within a direct realist view is offered by Bill Brewer.23 Brewer claims to be offering
an account of how perceptual beliefs are justified in an internalist sense, while
avoiding the traditional foundationalist (and representationalist) appeal to inference
from introspective knowledge of the character of subjective experience, an appeal
that he regards as hopeless.24
Brewer’s view can be viewed as an attempt to base the justification of such
claims on the distinctively presentational character of perceptual experience. The
initial idea is that perceptual experience is essentially perspectival and egocentric in
character: it presents physical objects and situations as standing in a set of spatial
16
relations that are centered on the perceiver [43]. Moreover, Brewer argues, these
presented spatial relations are in fact essential to picking out specific physical
objects in a way that makes determinate beliefs about those particular objects even
possible, since merely qualitative descriptions of objects, however complicated they
might be, could never guarantee unique reference [44-45]. Instead such specific
reference must be fundamentally demonstrative in character, appealing to the
egocentric spatial relations presented in experience.
So far, this seems to me plausible enough, but what does it have to do with
the issue of justification? Brewer’s claim is that
. . . egocentric spatial perception displays its objects as
epistemically accessible to the perceiver. . . . in veridical perception,
we are presented with things “out there” in such a way that we
grasp immediately how we are right about the way they are. [43]
Instead of the classical foundationalist’s reliance on inference,
The internalist requirement is met directly instead, by the
presentation of objects of experience as accessible to us, in virtue of
the egocentric spatial relations between them and us which are
displayed in experience. [43-4]
Here it should be noted that Brewer’s somewhat idiosyncratic version of internalism
in application to perception is that “the perceiver must know how he is right about
the way things are in the world around him” [41].25
How are we to understand this? It is reasonable enough to say that
perceptual experience seems to present objects as accessible to us, even though the
full story of how they are thus accessible (if indeed they are) and of how we are right
17
(if indeed we are) seems to demand further elements of a broadly causal sort that
are not in any clear way reflected in the presentational experience itself. But the
main problem, as the “seems” and the parenthetical qualifications (which are mine,
not Brewer’s) suggests, is that nothing about these facts of phenomenology offers
any apparent reason that counts against the possibility that the experiences in
question are deceptive or illusory in a way that would mean that the objects that
they seem to present do not genuinely exist. If this possibility were realized, and if
the rest of Brewer’s view is correct, then the upshot would be that the beliefs whose
attempted reference to objects is based on those experiences in fact fail to refer to
specific objects at all. And if this were the case for all of our perceptual experiences,
then the result would be that we fail to have any determinate beliefs about
particular objects in the world. This is no doubt an intuitively implausible result,
but it cannot be assumed to be false in the present context26 without begging the
essential question. Thus Brewer does not seem to have given any account of why
perceptual experience as such yields any justification or reason of an internalist sort
for thinking that the material objects that it seems to present are genuinely there.
The key assumption underlying the foregoing objection is that veridical
perceptual experiences, those for which the objects that seem to be presented are
really there, and non-veridical experiences, those for which they are not, might be
entirely indistinguishable from each other from a subjective standpoint,
indiscernible to the people who have them, in which case the occurrence of such an
experience would in itself yield no internalist reason or basis for thinking that the
actual situation is one way rather than another.27 Brewer, however, rejects this
assumption. He grants that the two sorts of experience cannot be distinguished in
18
an infallible or indubitable way, but argues that justification does not demand
infallibility or indubitability. And if such a demand is set aside, then, he argues, the
person whose experience is veridical can be justified in the way already described
and hence can know that the objects in question are genuine and hence also know on
that basis that his experience is veridical; whereas such justification and knowledge
is not, of course, available to the person whose experience is non-veridical (even
though it will mistakenly seem to him that it is). As Brewer says in a reply to
Richard Fumerton:
When having a vivid hallucinatory experience, a person does not
have the same reasons for empirical belief as she does when she is
actually perceiving the way things are in the world around her.
For, in the veridical case, her epistemic openness to the way things
are out there is evident to her, whereas, in the hallucinatory case,
she merely seems to be open to the way the world is.28
As he suggests at the end of this reply, his view involves “a more radical type of
externalism” than epistemic externalism of the reliabilist sort (namely, I take it, an
externalist view of content), one in which “a person’s subjective-experiential
condition in perception is itself constituted by her relations with the mind-
independent things in the world around her.”29
It is easy, however, to see that this move will not do, at least if it is a
genuinely internalist reason for thinking that material objects exist that is in
question. The problem, of course, is that even if it is granted that Brewer has
specified a difference between a veridical perceptual state and a non-veridical one,
this difference is not discernible to the individuals in question in the way that an
19
internalist justification requires. Contrary to Brewer’s suggestion, such a claim
need not be based on a demand of infallibility or indubitability. The problem is
rather that there need be no internally detectable difference of any sort for the
persons in question to appeal to, not just one that is infallible. True, the person who
has the veridical experience can claim correctly to be genuinely open to the world
and so to have the sort of reason for and consequent knowledge of the veridicality of
his or her experience that Brewer specifies; while the person who has the non-
veridical experience will in fact be incorrect in making such claims. But it remains
the case that if the issue were explicitly raised, neither of the persons would be able
to tell in a subjectively accessible way on the basis of the presentational character of
the experience alone which situation he or she is in. Thus each of them not only
fails to have what Brewer calls a “skeptic-proof guarantee of truth” [52], but in fact
fails to have any genuinely internalist reason at all. Again we seem to be left with a
skeptical result that is not mitigated to any serious extent by the fact that we may,
for all we can tell, be able to make claims of justification and knowledge that are
correct in senses that we cannot genuinely recognize.
V Both Huemer and Brewer attempt to rest the justification of claims about the
material world on what might be described as full-blown perceptual experience: the
perceptual experience that seems to present physical objects and situations in
physical space. Huemer regards such experience as propositional even though non-
conceptual, whereas Brewer regards it as conceptual and presumably also as
propositional. A third, quite different view, but still a version of direct realism as
understood here, is rather tentatively defended by Steven Reynolds.30 Reynolds
attempts to base the justification of perceptual beliefs on perceptual experience
20
conceived in a thinner, more austere way: roughly, in the visual case, as the
experience of patches of color of various sizes, shapes, and hues, arranged in a
person’s “visual field.” He characterizes such experiences as non-propositional and
non-intentional, and I believe that he would say that they are non-conceptual as
well.
This is essentially the same sort of experience that the most standard forms
of representationalism attempt to characterize in terms of sense-data and the like
and appeal to as the basis for their envisaged inference to the “external world.” I
have already said that I think that a consciousness of this sort of experience
normally exists in ordinary perception, albeit very much in the background, and it is
interesting to speculate as to how it relates to the richer level of experience to which
Huemer and Brewer appeal. My tentative suggestion would be that the richer level
of experience is in some way an amalgam of this thinner sort of experience with
conceptual elements: what C. I. Lewis, among others, used to describe as the
“conceptual interpretation of the given.” (Though how these elements are fused into
a phenomenologically seamless result is not easy to say.) Reynolds attempts to
explain how beliefs about material objects can be justified by non-propositional
experiences of this sort, but I think that the account, if successful, would apply just
as well to the justification of the richer variety or level of perceptual experience.
Reynolds suggests that the claims about material objects that we arrive at on
the basis of non-propositional experience reflect learned recognitional skills, skills
that are at least somewhat analogous to those involved in such things as playing the
piano or speaking a natural language [282]. Like other skills, these recognitional
skills could be captured in rules, though the person who has the skills need not be
thought of as having any very explicit conception of these rules. I think that this
21
picture is at least largely correct, that in arriving at claims about the material world
in response to the non-propositional level of experience we are guided by a tacitly
understood correlation of some complicated sort between experiential content and
material situations, with the only real question being whether this correlation is, as
Reynolds suggests, learned, or whether it is not instead partly or even largely
innate.
But what are the implications of this picture for the justification of the
resulting beliefs (and propositional perceptual experiences)? Reynolds’s suggestion
is that the resulting claims are epistemically justified just in case they in fact
conform to the rules that describe the recognitional skill in question, that is just in
case they fit the correlation between non-propositional experience and material-
object claims that (we confidently think) is shared within our epistemic community.
In his view, the epistemic goal of truth comes in only as part of the causal
explanation of why we adopt the practice of belief acquisition that involve these
rules: it is adopted because following such rules in fact tends to produce true beliefs
[288].
But this account is not enough to yield a genuinely internalist alternative to
representationalism (something, to be sure, that Reynolds makes no very explicit
claim to be doing). I have no real quarrel with saying that there is a species of
justification that results from conformity to this tacitly accepted correlation or set of
rules, something perhaps close to what Tyler Burge and others have in mind by
speaking of entitlement.31 But whether the justification (or entitlement) that results
in this way is epistemic in character must surely depend in the end on whether or
not the correlation between experience and material objects or situations reflected in
22
the correlation in question is indeed accurate or reliable in the sense that the claims
about the material world arrived at on that basis are in fact likely to be true. And
for the resulting justification to be genuinely internalist in character, it seems that
there must be good internalist reasons for thinking that this is so. Thus, I suggest,
we are led inexorably back to the classical representationalist project of trying to
show how an inference from the features of non-conceptual and non-propositional
experience to claims about the material world can be justified. Perhaps ordinary
people need not actually be able to make this inference in order for them to be in
some sense entitled to their beliefs, but that it be possible to make it is, I am
suggesting, a necessary condition for this entitlement to count as genuinely
epistemic, from an internalist standpoint.
VI I have now examined, in the previous three sections, three specific accounts
of how perceptual claims about the material world might be justified within a direct
realist view in ways that differ from that advocated by the representationalist and
have argued that none of these accounts is successful. These results obviously do
not in themselves establish that there is not some other possible direct realist
account that is more tenable, even though I have been unable to find one. But I
want to suggest briefly that there is some reason, though hardly a conclusive one, for
thinking that any further such account will be in the vicinity of one of the ones just
considered and likely open to the same objections.
The reason in question is based on the idea that versions of direct realism can
be usefully distinguished by what they say about the nature of perceptual experience
and its role in justification. If such experience is to play a justificatory role, then the
direct realist must seemingly either (i) ascribe to experience a propositional content
23
of an internally accessible sort and appeal to that content for the justification of
perceptual beliefs, or (ii) ascribe to perceptual experience a propositional content
that is partly external in the content-externalist sense and appeal in part to that
external content for the justification of perceptual beliefs, or (iii) attempt to justify
perceptual claims by appeal to only non-propositional experiential content.
Huemer’s account is of sort (i) and faces the problem, in my view insoluble, of how
the subjectively accessible propositional content of the perceptual experience is itself
to be justified. Brewer’s account is of sort (ii) and faces the problem, which I again
regard as insoluble, that the sort of justification it offers will not be accessible to the
believer in the way that a genuinely internalist view requires. And a version of
alternative (iii), such as that advanced by Reynolds, seems to lead directly back to
representationalism in the way suggested. I can see no further possibility that is
compatible with the idea that perception experience is itself somehow a source of
justification. As already suggested, this is not intended to be anything like a
demonstrative argument. But it may suggest that in investigating the specific views
I have considered, more progress has been made toward assessing the overall
viability of direct realism than might otherwise have been thought.
Is there any further direct realist alternative, one that avoids any claim that
perceptual experience has a content that plays a role in justification, while still
claiming that perception is somehow a source of justification? The obvious problem
is that it is extremely unclear where such justification is supposed to come from.
Moreover, I would suggest, it is after all pretty obvious on reflection that
perceptual experience does contribute in an important way to the justification that
perceptual beliefs seem intuitively to have. For example, as I look out on this room
and form various perceptual beliefs concerning the presence of people and chairs and
24
walls and windows, my reasons or apparent reasons for thinking those various
things are true surely depend in a fundamental way on the presence in my visual
field of what might be characterized as distinctively shaped patches of color. These
phenomenal elements seem to present to me the objects in question and even
perhaps to be in some way identical with them. I have argued that this seeming
presentation cannot simply be accepted at face value. But it still is, I suggest,
abundantly obvious that the presence in my experience of elements of this kind
plays an essential role in the only sort of reason or basis for thinking that my
perceptual claims are true that I even seem to myself to have. And once direct
realist views of the sorts already considered in the previous three sections are set
aside, only the representationalist account of how such a reason could be genuinely
cogent seems to remain. The difficulties that face such a view are extremely
familiar and obvious, and I do not mean to take them lightly. But I would also
suggest that far, far too much of the discussion of these issues, from the time of
Descartes and Locke to our own, has been concerned with ways of attempting to
evade the need for such an account and far too little with actually attempting to give
one—with the various views that fall under the rubric of direct realism being only
the latest attempts at such evasion and likely, I think, to be no more successful in
the end than the idealist and phenomenalist views that preceded them.

NOTES
1 I am not assuming here that a reason or basis for thinking that a belief is true must
take the form of another belief; on the contrary, anything to which one has cognitive access that provides a rational basis for thinking that a belief is true will count as such a reason.
2 The representationalist does not, of course, deny that material objects are genuinely perceived, but only attempts to give an account of how such perception works and of why it is not direct or immediate in the way that it might seem commonsensically to be. It is also worth noting that while the most standard formulations of representationalism appeal to sense-data (or to entities of arguably the same basic sort, such as the “ideas” of the British empiricists), neither the sense-datum theory nor the more general “act-object” picture that underlies it is in any way essential to the basic representationalist view. If, for example, one adopts instead an “adverbial” account of perceptual experience, the representationalist view can still be formulated as the theses (a) that what one is most directly aware of in perceptual experience is the adverbial features of experiential states (which are, of course, quite distinct from material objects) and (b) that any good reasons we may have for believing that material objects of various sorts exist depend on inference from facts about these adverbial features. (It will be convenient to continue to use the term “object” to refer to whatever it is of which one is directly aware in perception, irrespective of which metaphysical category it may belong to.)

What the regress argument shows is that there must be beliefs that are justified in some way that does not rely on further beliefs, not that there are beliefs that are justified in the absence of any sort of good reason or basis for thinking that they are true.

34 (2000), pp. 517-49. Pryor’s claim, defended on intuitive grounds, is that merely the occurrence of “an experience as of p’s being the case,” where p is one of a large class of
26
propositions about material objects that are “basically represented by our experience,” yields prima facie justification for believing p. But while I agree that there is a commonsense intuition of this sort, I do not think it is enough to obviate the need to explain just how the justification is supposed to work, how the occurrence of such an experience yields a reason or basis for thinking that the proposition in question is true. And in the end, I think that the representationalist’s account, based on the qualitative character of the underlying experience, is the only one that is available. (See the discussion, below, of Reynolds’s appeal to recognitional skill.)
14 See the paper cited in note 9. 15 Though this might be a pyrrhic victory for the representationalist if the awareness of
sense-data (or adverbial features) cannot itself be justified by appeal to something like the Cartesian notion of immediacy.

17 Though the relation between a belief and the corresponding experience is not inferential, according to Huemer, it is logical in a broader sense: the non-conceptually represented content of the perceptual experience is either the same as or, normally, a more determinate version of the conceptually represented content of the belief, so that the former entails the latter.
18 Many are likely to have doubts about the claim that perceptual experiences have propositional content without being conceptual; indeed, I have heard it claimed that such a view is simply incoherent, that only representations that involve concepts can have propositional content. In the end, I am inclined to agree that this is so and hence that Huemer’s view on this point is mistaken. But I do not think that this is immediately obvious or that there is any very simple way to argue for it.
19 One thing worth noticing here is that if this principle were correct, and assuming that the justification it speaks of is supposed to be epistemic justification in the sense of there being a good reason or basis for thinking that the claim in question is likely to be true, then it would follow from the principle that a suitably abstract version of the representational content of the perceptual experience would, after all, also be justified in the sense just indicated—which is why I regard this principle as a second, quite different response to the question of how perceptual experiences are justified. (“Suitably abstract” because this point pertains only to the part of the experience’s content that is at the same level of abstraction as the belief and would not extend to the more specific content of the experience, the ways in which it is more determinate than the belief. But it is hard to see how the more abstract content could be justified if this specific content were not.)
20 See the paper cited in note 9; and my book In Defense of Pure Reason (Cambridge: Cambridge University Press, 1998), chapters 4 and 5.
21 To be fair to Huemer, I should note that he seems to be operating with what has become known as a deontological conception of epistemic justification, one according to which a belief is justified if the believer is epistemically blameless in holding it. If there were no way to discriminate among seemings with respect to whether they yield genuine reasons for thinking that the corresponding claims are true, then it would be plausible enough that a person who accepted beliefs on the basis of seemings generally would be epistemically blameless simply because that is the only epistemic alternative that would be open. As I have argued elsewhere, however, being epistemically blameless (or satisfying other similar deontological requirements) is not enough for genuine epistemic justification: the aim of epistemic justification is truth, and the connection between blamelessness and truth is far
27
too tenuous—as indeed the point just made illustrates. (See my paper “The Indispensability of Internalism,” forthcoming from Philosophical Topics.) I have taken Huemer to be primarily concerned with genuine epistemic justification and have interpreted his view accordingly; to take him to be concerned only with epistemic blamelessness would mean that his view fails to be a version of direct realism in the sense explained above, i.e., no longer a genuine epistemological alternative to representationalism.
22 Making the “Phenomenal” part of the label for the principle somewhat misleading. 23 In his book Perception and Reason (Oxford: Oxford University Press, 1999) and in
his earlier article “Foundations of Perceptual Knowledge,” American Philosophical Quarterly, vol. 34 (1997), pp. 41-55. For reasons of space, I will mostly follow the simpler version of the view presented in the article (bracketed references in this section are to its pages), thus leaving aside many further interesting details, arguments, and ramifications, which do not, however, in my judgment affect the central issue I am concerned with. See also a book symposium on Perception and Reason in Philosophy and Phenomenological Research, vol. 63 (2001), pp. 405-64.
24 See the discussion in Perception and Reason, pp. 112-29. 25 In Perception and Reason, Brewer offers a further argument (in chapter 3) for the
thesis that the same relations between perceptual experiences and perceptual beliefs that determine the specific content of those beliefs must also yield reasons for thinking that those beliefs are true. This argument seems to me objectionably verificationist in character, but I have no room to discuss it here.
26 As Brewer sometimes seems to do. See, e.g., Perception and Reason, pp. 20-21. 27 I do not mean to suggest here that there might not be further reasons of some sort for
favoring one of these alternatives over the other; but such further reasons would have to appeal to more than the experiences themselves.

This may lead back to something like Brewer’s view, but Burge does not say enough to make it possible to be very sure.
